Re: How to turn off WiFi in async MQTT?

Followup on my last message - Mike, I see that you are going to be receiving a Pyboard D; at best you would need some kind of adapter to use my I2S daughterboard. Otherwise I can't say anything regarding compatibility, but it won't be plug-and-play like with the original pyboard.

Re: How to turn off WiFi in async MQTT?

Scheduling at the Python level is now much improved. I have gotten that impression, though I have not had a chance to dig in to see how it works and how I might be able to use it. At this point, the biggest hurdle for me to revive my project is to figure out how to incorporate my 3.5-year-old work ...

Re: How to turn off WiFi in async MQTT?

You're probably aware that @blmorris did some work on Pyboard I2S Definitely. I reviewed his work extensively. His I2S implementation was definitely more ambitious than mine. I only implemented master I2S, no slave. I tried to pattern the I2S uPy API arguments and methods using the I2S API that he ...

Re: Questions and wish list about Pyboard D

I would assume software wise I2S implementation would be very similar infact on the STM32F405 it is a type SPI transfer. You might assume that... until you realize that I2S is used for streaming audio and is therefore necessarily isochronous, and if you want to listen to your audio track for any si...

Re: Olimex STM32-E407

OK. So what do we have to do to get Ethernet up and running of the E407 ? To be honest, I can't help much with that yet except to suggest digging into the ST's Cube libraries for the STM32F4 and look for anything having to do with ethernet/MII/RMII support. The relevant components aren't currently ...

Re: Olimex STM32-E407

Thanks!
As for Olimex, AFAICT they are a fine outfit, with inexpensive and well-documented products and committed to open-source development. My experience with them is limited, but I have no reason not to recommend them.

Re: Olimex STM32-E407

Hi Martin- No, while I did manage a simple port to the Olimex board I didn't attempt to tackle the ethernet subsystem. I did get the consulting project, but the focus of my work involved much more hardware design and integration rather than software development. I built a carrier board for the Olime...

Re: PYBv1.1 with LCD32MKv1.0 LCD Touch Skin

Yes, you should be able to use the LCD skin in the 'Y' position and leave the servo pins free for a servo. Just note that the 'Y' position is rotated 180 degrees relative to the 'X' position.

Re: About the I2S on WiPy.

AFAIK, I2S is not supported by MicroPython on any port yet. There is this closed Github PR where somebody implemented it for the stmhal port but unfortunately apparently he abandoned it. Hi all- FWIW, that is my PR, and yes, it has been pushed to the back burner for the time being. Haven't been tra...
